速度是3D程序中最重要的指标，你必须限制绘制的多边形的个数，或者提高显卡绘制多边形的效率。显卡最近增加了一个新的扩展，叫做顶点缓存VS，它直接把顶点放置在显卡中的高速缓存中，极大的增加了绘制速度。

-The speed is the most important indicator of the 3D program, you must limit the number of polygon draw, or to improve the efficiency of the graphics draw polygons. Graphics card recently added a new extension, called the vertex buffer VS it directly to the vertex placed on the graphics card in the cache, which greatly increased the speed of rendering.
